It creates or enables a privileged hidden account, weakens RDP controls, and exposes port 3389. - **Trigger:** npm installation on Windows runs postinstall. - **Impact:** Creates an accessible privileged RDP backdoor and weakens remote-session protections. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-14T02:04:23.045Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** elevated PowerShell, registry, local-account, and firewall mutation - **Attack narrative:** Installing the package triggers an elevated installer without a separate user command. That installer enables or creates an administrator-capable RDP account, adds it to Administrators and Remote Desktop Users, hides it from the sign-in list, enables RDP, disables NLA, allows permissionless shadowing, and creates inbound firewall rules on port 3389. A preset administrator password is bundled in config.json, making this a concrete remote-access backdoor chain. - **Rationale:** The malicious remote-access configuration executes automatically at install time and materially weakens host authentication and visibility. It is not merely an installer primitive or an explicitly invoked setup command. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json, payload/bikli-cli-installer.exe, payload/RDPWInst.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall automatically invokes privileged install logic., Install enables or creates an administrator/RDP user and hides it from the sign-in list., Bundled wrapper disables NLA and enables permissionless RDP shadowing., Install opens inbound TCP and UDP firewall rules for RDP on port 3389., The shipped config contains a preset administrator password. - **Evidence against:** No HTTP, fetch, or other source-level data-exfiltration endpoint was found., The behavior is implemented in readable JavaScript rather than an opaque downloaded payload. ## Public findings ### 1.
